That’s what they do most forgiving bullet I’ve ever loadedFinally got to the range today to try Hammer Hunters for the first time.
Custom 300 PRC with 26" Bartlein 5R, CF, 9 twist, Sendero Contour.
Bullets: 199 Hammer Hunter
Primer: CCI 250
Powder: N565 (started at 79.0 grains)
Seating Depth: .020 Jump
79.0 grains 2995 FPS
79.5 grains 3050 FPS (not sure why this was so fast)
80.0 grains 3037 FPS (bolt getting sticky)
80.5 grains 3070 FPS (heavier bolt lift)
81.0 grains 3102 FPS (even heavier bolt lift)
Plan to dump the rest of what I loaded and go back to 79-79.5 grains. All shots were at 100 yards, same POA. Impressive how tight the group is with a 2.0 grain spread! The "flyer" was the weird second shot at 79.5 grains. Even with it counted, the group was right at an inch.
